Indian teen arrested in US for cyber attack choking 911 lines

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

Bengaluru, Feb 4: The possibility of defeated MLA CP Yogeshwar being inducted into chief minister BS Yediyurappa’s cabinet is causing ripples within the ruling BJP, with many legislators, especially from Kalyana-Karnataka region, raising a banner of revolt.

Several MLAs led by Surapur legislator Narasimha Nayak, also known as Raju Gouda, held a meeting at the Legislators Home on Monday and voiced their opposition.

"When there are more than two dozen MLAs aspiring for a cabinet berth, making a former MLA a minister is beyond logic," Gouda said. "We will convey our feelings to Yediyurappa and state BJP president Nalin Kumar Kateel." Murugesh Nirani, Paranna Munavalli, Rajkumar Patil, Dattatreya Patil Revoor, Basavaraj Mattimud are among others who attended the meeting. MP Renukacharya, political secretary to the CM and Honnali MLA, was also present at the meeting. "Some more MLAs will join us when we meet again tomorrow," Gouda said.

The MLAs highlighted the issue of caste and regional imbalance in the council of ministers to further their cause. With four from Bengaluru and three from Belagavi district set to take oath on February 6, the share of MLAs from these districts in the cabinet will rise to seven and five respectively. Currently, 16 districts have no representation.

Sources say Yediyurappa and BJP’s national leadership decided to reward Yogeshwar with a cabinet berth for his "active" role in getting 17 Congress-JD(S) MLAs to resign and join the BJP, enabling the party to grab power. The party also believes he has the potential to become the Vokkaliga face of the BJP in the Old Mysuru region, where the party’s organisation is weak.

If Yogeshwar is inducted, he will be the second former MLA to make it to Yediyurappa cabinet after deputy CM Laxman Savadi, who lost the 2018 assembly polls. Several party MLAs were unhappy with Savadi’s elevation and are now upping the ante against the party leadership.

"Let Yogeshwar be made Rajya Sabha or council member. We have no problem. But making him minister is not acceptable. If they want to make defeated MLAs ministers, then why not AH Vishwanath and MTB Nagaraj, whose sacrifices brought BJP to power?" said Gouda.

Reports say Yediyurappa has promised Vishwanath and Nagaraj, the disqualified MLAs who lost the bypolls, that they would be made ministers in June. Both met Yediyurappa and secured this assurance. The two were demanding that they be inducted into the cabinet on Thursday.

Meanwhile, Vijayapura MLA Basavanagouda Patil Yatnal urged the CM to evaluate the performance of existing ministers and drop those found non-performing. "Many ministers don’t even come to the Vidhana Soudha. What is the use of having such ministers?" he asked.

Yediyurappa also continued to face pressure to induct Athani MLA Mahesh Kumatalli into the cabinet. The Jarkiholi brothers, Ramesh and Balachandra met Yediyurappa separately on Monday with a request to make Kumatalli, their confidant, a minister.
